Conducting internal calls
If several telephones are connected to your FRITZ!Box, you can conduct (free) internal calls between the telephones. For example, you can use a cordless telephone to call a telephone connected to an analog extension of the FRITZ!Box.
1 Conducting internal calls
Configuring a telephone to use the keypad function
Keypad sequences are strings of characters and numbers that you can use to enable or disable functions. You can use keypad sequences immediately with telephones, such as FRITZ!Fon C5, that are registered with the base station of your FRITZ!Box. If you are using a cordless telephone that is not registered with the FRITZ!Box's base station, you must configure the keypad function first:
- Configure the telephone so you can send keypad sequences (sequences of characters and numbers, such as *121#) and enter special characters such as * and # with it. On many telephones, you can configure this function in the menu "Operation at a PBX > Dialing options > Dial * and #".
Making internal calls
- If all of the telephones connected to the FRITZ!Box should ring, enter **9 to initiate a broadcast call. The call is conducted with the party who answers the telephone first.
- If several telephones connected to the FRITZ!Box (call group) should ring, enter ** and the quick-dial number of an internal call group, for example 701. The call is conducted with the party who answers the telephone first.
- If a specific telephone should ring, enter ** followed by the internal telephone number of the telephone.
To call a telephone connected to the "FON 1" port, enter **1.
Note:You can find the internal numbers of the telephony devices in the FRITZ!Box user interface under "Telephone Book > Internal Numbers".
